Description

technical field [0001] The invention relates to an anti-porcine pseudorabies composition, a feed additive containing the composition, a preparation method and application thereof, and belongs to the field of feed additives. Background technique [0002] With the development of society and the improvement of people's living standards, more and more people turn their attention to food safety issues. The pig industry occupies a relatively heavy share in my country's breeding industry. In 2009, Henan Province alone produced 4,103,200 tons of pork. It can be seen from this that my country's annual demand for pork is very large. However, with the increasing demand for pork year by year, there are more and more problems in the process of raising pigs. Among them, porcine pseudorabies is an acute infectious disease, which has caused huge economic losses to the pig industry. [0003] Pseudorabies virus belongs to the family Herpesviridae (Herpesviridae), the genus of porcine herpesv...

Problems solved by technology

Among them, the excessive use of western medicine has brought great dietary hazards to the consumption of pig products, and drug residues have become one of the main factors affecting the safety of pig products

The early effect of vaccination is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reactions in weaned pigs; moreover, the vaccine has high requirements for storage conditions, and it needs to be refrigerated at 2-8°C and kept at room temperature. It will lose its effect after a while

Chinese herbal medicine feed additives are also one of the current research directions, but because there are many types of Chinese herbal medicines, the effects of the same Chinese herbal medicines on different poultry diseases are very different, and the immune effects of Chinese herbal medicines on diseases are extremely limited, so its application also has great potential. certain limitations

Injection of egg yolk antibody is also a relatively common method, but the immune effect of a single injection of egg yolk antibody sometimes cannot meet the actual needs
